INTRODUCTION
[0002] Powered windows have not yet been widely accepted in the
marketplace. The reasons are numerous, but may include product
expense, consumer mistrust of the safety and/or security of the
technology, or other reasons. Many consumers view windows as a
building material that is simply opened or closed when needed and,
in the interim, largely forgotten, since the window performs little
function other than ventilation. Additionally, many automated
windows neither control nor adequately address energy, security,
performance, and/or impact resistance automatically, without
constant user input.

[0013] FIG. 7 is an embodiment of a network in which the various
systems and methods disclosed herein may operate.
DETAILED DESCRIPTION
[0014] The technologies described herein are directed to a powered
window system or unit that is intended for schools, health care,
hotels, light commercial, residential, and other energy-conscious
facilities. In addition to high air resistance, water resistance,
and structural performance, examples of such window systems manage
any or all of security, ventilation, energy savings, energy
generation, and may meet American with Disabilities Act (ADA)
requirements.
[0015] The powered window systems may be installed in a vertically-
or horizontally-operating orientation. High performance insulated
glass may be installed in the window sash. Examples of the window
system may include a movable panel that covers and uncovers the
window sash opening. The panel may provide insulation, improve
security, and increase storm and/or impact resistance, among other
functions. In addition, the panel can include a solar panel,
decorative panel, screen, etc. Multiple panels can be utilized.
Other accessories (such as ventilators) may be added to interior or
exterior insulated panels. Ventilators may be used to exchange
indoor and outdoor air at each discrete window unit, for
ventilation, free cooling, etc. Additionally, warm air that may be
present within the window unit itself due to solar heat gain could
be vented to optimize energy usage and comfort within the building.
Additionally, an insect-resistant screen may be unrolled
automatically as either or both of the window sash or panel is
opened, to prevent intrusion of insects.
[0016] Both the window sash and the panel cover may be operated by
electric motor drive systems or mechanical drive systems to slide
those elements remotely and independently. The motor, control
components, sensor, and so on may be powered by a dedicated (e.g.,
battery) power system, building power system, and/or one or more
solar cells. The solar cells may be integrated into an exterior
portion of the window to maintain and charge the power system
battery if present, or deliver electrical power back to the
building power grid. The window system manages and conserves
energy, and provides impact resistance, privacy, and security for
the building, even when the sash is open. In certain examples, the
window system may be controlled remotely. The movable window sash
and panel may operate separately or together. An energy and/or
security management system may control the window with little or no
energy consumption. This window system may rely on sensors and a
CPU to operate the window, communicate status, etc. The sash and
panel may be controlled by an energy and security management system
that may be integrated and powered with solar cells, building
power, or otherwise. In various examples, this management system
may open and close the window sash, open and close the panel,
and/or manage the energy collection/distribution system.
[0017] The window system includes a frame that holds the window
sash and the panel. The frame also contains electric motor drive
systems or mechanical drive systems. One drive system may power the
window sash to open and close the window for ventilation. Another
drive system may power the panel to protect and/or insulate the
window. In another example, a single drive system with a clutch
mechanism may be used to actuate the window sash and panel.
Additional drive systems or actuators may be used for other window
functions if required or desired. The window frame also provides
weatherstripping to control air flow and water control to prevent
water from penetrating the structure in which the window is
mounted. In addition, the window frame also provides insulation
across the overall frame to insulate the window system.
[0018] With these broad concepts in mind, several examples of
powered window systems are described below. For example, FIG. 1 is
a partial cut away front view of a powered window unit 100. The
window unit 100 may include a window frame 102, a movable window
sash 104, a movable panel (not depicted), a drive motor 106, a
drive system (depicted generally as 108), and a
controller/management system 110. As described above, the drive
motor 106 and drive system 108 can be a combined system that
operates both the sash and the panel. Examples thereof are
described below. The various elements are contained within the
single window unit 100 to be installed within a building envelope.
In general, the window system 100 of FIG. 1 is depicted in a
vertical orientation, but may also be installed in a horizontal
orientation so as to slide side-to-side. Further structure,
functionality, and aspects of these and other components are
described below.
[0019] The window frame 102 includes weather-resistant structural
members joined in a manner to hold the other components. The frame
102 is secured to the building structure to provide a
weather-resistant seal, typically at one or more side jambs 112, a
head 114, and a sill 116. Weatherstripping and insulation may also
be incorporated into the frame 102. FIG. 1 depicts a view of the
window 100 from an interior side, and may include an interior panel
118 proximate the sill 116. In this example, the panel 118 is
insulated and includes the window management system 110, or may
also include one or more basic control elements (e.g., an up/down
switch). Different types of control elements are described below
and are positioned so as to be more easily accessible to a user.
Disposing the control elements lower on the window 100 may enable
them to be more easily actuated by a person with disabilities, in
compliance with the American with Disabilities Act. Additionally,
the interior panel 118 may be decorative or may be designed to be
visually and structurally similar to the wall in which the window
system 100 is installed. A service panel (removed in FIG. 1 for
clarity) can enclose the motor 106 and drive system 108. The
interior panel 118 and/or service panel may be removed to access
interior cavities of the window system 100, as well as any
mechanism, electronics, motors, and other elements disposed
therein, for service and replacement.
[0020] The sash 104 is generally installed on an interior (relative
to the movable panel) of the window unit. This interior-mounted
sash 104 may be an insulated glass assembly. The glass assembly may
be of various thicknesses and may incorporate various high
performance enhancements like glass coatings, gases between the
panes of glass, and/or vacuum insulated glass. Coatings may be
those available in the art, including but not limited to colored,
electrochromatic, and reflective. In certain examples, the sash 104
may be substantially frameless, or the frame of the sash 104 may be
hidden within the window frame 102. The sash 104 slides up and down
or side-to-side in the frame 102 (depending on the installation
orientation) and may be sealed with weatherstripping. The sash 104
may be attached to a sash drive system (e.g., the drive system 108)
disposed within a drive cavity 120 of the window frame 102. The
drive system 108 may be connected to the sash 104 within the side
jambs 112 so as to be hidden from view during use. In certain
examples, it may be desirable that the window sash 102 is not
movable, e.g., in high-rise building applications where opening
windows may be undesirable. The window system 100 may still perform
other functionality as described herein, even though the sash 104
is not movable.
[0021] FIGS. 2A and 2B are side sectional views of the powered
window unit 100 of FIG. 1, with the sash 104 and the panel 122 in
upper closed positions and lower open positions, respectively. A
number of elements depicted in FIGS. 2A and 2B are described above
in the context of FIG. 1 and thus are not necessarily described
further. FIGS. 2A and 2B are described simultaneously. The panel
122 may be made of an insulated material with structural impact
resistance, which may be configured to withstand, e.g.,
hurricane-force winds or projectiles such as bullets, bricks, or
other damaging implements. The panel 122 may be manufactured of a
composite material such as Kevlar or other robust protective
plastic. Additionally, the panel 122 may be manufactured of metal,
which may be selected or otherwise treated to resist environmental
conditions such as salt-spray, ultraviolet rays, wind, etc. The
panel 122 is configured to slide in the frame 102 on the exterior
side 124 of the window unit 100 in front of the movable sash 104.
The panel 122 may be moved by the motor 106 and drive system 108 (a
clutch or other disengageable element may be utilized to separate
movement of the panel 122 from movement of the sash 104). In an
alternative example, the panel 122 may utilize its own dedicated
motor and drive system. Such examples are depicted below. The panel
drive system (if used) may also be disposed in the drive cavity
120. The panel 122 may be manufactured of several materials, glass,
or solar panels. Additionally, the panel 122 may be a decorative
and/or functional (e.g., bug-resistant) screen material. The panel
122 may also be a steel or other metal security mesh or bar
structure to prevent unwanted ingress by an intruder. Multiple
parallel panels may be utilized. For example, an outer decorative
or architectural panel may be utilized in conjunction with an inner
protective panel.
[0022] An exterior panel 126 may incorporate a solar panel and/or
may be configured to resemble the exterior structure of the
building in which the window system 100 is installed. As with the
interior panel 118, this panel may also be insulated. In examples,
this panel 126 may be removeable, but for security purposes, it may
be desirable that only the interior panel 118 is removeable. The
interior panel 118, exterior panel 126, sill 116, and side jambs
112 at least partially define a receiver 128. The receiver 128 is
configured to receive both the panel 122 and the sash 104 when
these components are in the open position. In examples,
substantially all of the panel 122 and sash 104 may be received in
the receiver 128 when in the open position. When in the closed
position, a lower portion of either or both of the panel 122 and
the sash 104 may still be disposed in the receiver 128 to maintain
stability of those elements. The drive cavity 120 may be access via
an access panel 128 on an interior side 130 of the window unit 100.
An exterior drive cavity panel 132 may be finished to match the
exterior aesthetics of the building, include a solar panel, etc. A
spring, balance, or other biasing element 134 may be connected to
either or both of the sash 104 and the panel 122. In the event of a
power failure, drive system failure, or other condition, a user may
activate a mechanical release that disengages the drive system 108
from the motor 106. The biasing element 134 would then force either
or both of the sash 104 and panel 122 into the open position to
allow for egress. In other examples, the weight of the sash 104 and
panel 122 may be sufficient to lower those elements by gravity once
released. The mechanical release may be desirable so a more routine
power loss (e.g., due to a storm power outage) will not open the
sash 104 and panel 122, thus maintaining security of the building.
A spring balance may also be used to minimize the amount of energy
required by the motor to raise or lower either the sash 104 or the
panel 122.
[0023] FIGS. 3A and 3B are front and top views, respectively, of a
motor system 200 of the powered window unit of FIG. 1. FIGS. 3A and
3B are described simultaneously. The motor system 200 is described
in FIGS. 3A and 3B in the context of a sash 202, but similar motor
systems can be used to move the panel. Additional motor system
configurations are depicted below in FIGS. 4A-4E. In FIGS. 3A and
3B, a single motor 204 is depicted. The motor 204 turns a shaft 206
that can include a number of gears. The motor 204 is powered and
controlled by, e.g., a 12 to 24V DC electrical current from a
window management system or controller (described below). A
sprocket system including two sprockets 208, 210 are rotated based
on rotation of the motor shaft 206. The sprocket system forms a
part of the drive system (depicted generally as 212). The drive
system 212 may be mounted in a drive cavity 214 of the frame 216 to
move the sash 202 up and down. In the depicted embodiment, the
drive system 212 may be installed behind an upper interior panel
that may be removed so as to access and service the drive system
212. The drive system 212 may include a system of belts, chains,
cables, or other elements which are attached to the movable sash
202 (at connectors 222, 224) through a system of pulleys,
sprockets, guides, cables, etc. In the depicted example, chains
218, 220 are utilized.
[0024] The drive system 212 may include an emergency egress button
or switch (not shown in FIGS. 3A, 3B). When actuated, the drive
system 212 may automatically open the window sash 202 (and panel,
if required) so as to allow egress through the window during an
emergency. The egress system may be electrically or mechanically
operated. If electrically operated, it may be desirable to include
a local battery to ensure that the egress system is operational in
the event of a loss of building power. A mechanical egress system
may disengage the window sash 202 from the drive system 212,
causing the sash 202 to fall from the closed position. In other
examples, the egress system may be actuated by sensing a force
applied substantially orthogonal to the sash 202 (i.e., by a panic
press or strike against the interior of the window). Such sensors
and accessories are described in more detail below. A panel drive
system is similar to the sash drive system 202 and may include a
similar emergency egress system. In another embodiment, the sash
and panel drive systems may be the combined into a single system.
Other drive systems are depicted in FIGS. 4A-4E, below.
[0025] FIGS. 4A-4E are schematic diagrams of window unit actuation
systems 300 for powered window units. In each figure, the sash
and/or panel is depicted in the closed position. In FIG. 4A, two
discrete actuation systems are depicted. As used herein, the
actuation system includes one or more motors and drive systems. In
the depicted example, a sash 302A and a panel 304A are depicted.
Each of the sash 302A and panel 304A are actuated by a dedicated
actuation system 306A, 308A, respectively. Both actuation systems
306A, 308A include a motor 310A, 312A, and a drive system 314A.
316A. The actuation systems 306A. 308A are substantially identical
in configuration, although larger motors and/or more robust drive
systems can be used if the weight of the moved sash 302A or panel
304A warrants. Each drive system 314A, 316A includes a pulley 318A.
320A connected to a motor shaft 322A. 324A. Although one pulley
318A, 320A is depicted, two pulleys may also be used. Cables 326A,
328A are connected at first ends 330A, 332A to the pulley 318A,
320A. At second ends 334A, 336A, the cables 326A, 328A are
connected to a lower portion of the sash 302A or panel 304A,
respectively. Central portions 338A, 340A of the cables 326A, 328A
are routed about pulleys 342A, 344A so as to reduce friction. The
pulleys 342A, 344A are generally fixed in position, for example, to
the window unit frame F. This particular configuration allows for
optimum sizing of the motors (as required for the weight of the
sash 302A and the panel 304A).
[0026] In FIG. 4B, two discrete drive systems are depicted,
controlled by a single motor. In the depicted example, a sash 302B
and a panel 304B are depicted. Each of the sash 302B and panel 304B
are actuated by a dedicated drive system 314B, 316B, respectively,
driven by a single motor 310B. As such, actuation systems 306B,
308B are substantially identical in configuration, although the
motor 310B should be sized for the heavier of the two components
(the sash 302B or the panel 304B), or the combined weight of both.
Each drive system 314B, 316B includes a pulley 318B, 320B connected
to the single motor shaft 322B. Clutches 346B, 348B are used to
engage the pulleys 318B, 320B so as to engage the pulleys 318B,
320B. Although one pulley 318B, 320B is depicted, two pulleys may
also be used. Cables 326B, 328B are connected at first ends 330B,
332B to the pulley 318B, 320B. At second ends 334B, 336B, the
cables 326B, 328B are connected to a lower portion of the sash 302B
or panel 304B, respectively. Central portions 338B, 340B of the
cables 326B, 328B are routed about pulleys 342B, 344B so as to
reduce friction. The pulleys 342B, 344B are generally fixed in
position, for example, to the window unit frame F.
[0027] In FIG. 4C, a single actuation system 306C is depicted for a
sash 302C, although a similar configuration may be used for a
panel. Additionally, a single motor with pulleys and clutches,
similar to that depicted in FIG. 4B may be utilized. The actuation
system 306C includes a motor 310C, and a drive system 314C. The
drive system 314C includes two chains 326C, 328C connected to a
motor shaft 322C by a sprocket 318C, 320C. The chains 326C, 328C
are connected at first ends 330C, 332C to an upper portion of the
sash 302C. At second ends 334C, 336C, the chains 326C, 328C are
connected to a lower portion of the sash 302C. Central portions
338C, 340C of the chains 326C, 328C are routed about sprockets
342C, 344C so as to reduce friction. Additional sprockets 350C,
352C can be disposed generally near the bottom of the window unit
frame F so as to enable a full range of motion and to further
reduce friction. The sprockets 342C, 344C, 350C, 352C are generally
fixed in position, for example, to the window unit frame F.
[0028] In FIG. 4D, a single actuation system 306D is depicted for a
sash 302D, although a similar configuration may be used for a
panel. Additionally, a single motor with pulleys and clutches,
similar to that depicted in FIG. 4B may be utilized. The actuation
system 306D includes a motor 310D, and a drive system 314D. The
drive system 314D includes two chains 326D, 328D connected to a
motor shaft 322D by a sprocket 318D, 320D. The chains 326D, 328D
are continuous and are routed about sprockets 342D, 344D, 354D,
356D so as to reduce friction. Additional sprockets 350D, 352D can
be disposed generally near the bottom of the window unit frame (not
depicted) so as to enable a full range of motion and to further
reduce friction. The sprockets 342D, 344D, 350D, 352D, 354D, 356D
are generally fixed in position, for example, to the window unit
frame F. Connectors 358D, 360D connect the sash 302D to the chains
326D, 328D, such that movement thereof moves the sash 302D.
[0029] In FIG. 4E, a single actuation system 306E is depicted for a
sash 302E, although a similar configuration may be used for a
panel. The actuation system 306E includes two motor 310E, 312A and
two drive systems 314E, 316E to drive a single sash 302E. The drive
system 314E, 316E each include a chain 326E, 328E connected to a
motor shaft 322E, 324E by a sprocket 318E. 320E. The chains 326E,
328E are continuous and are routed about sprockets 350E. 352E so as
to reduce friction. The sprockets 350E, 352E are generally fixed in
position, for example, to the window unit frame F. Connectors 358E,
360E connect the sash 302E to the chains 326E, 328E, such that
movement thereof moves the sash 302E. Each motor 310E, 312E may be
sized so as to be able to lift and lower the sash 302E alone,
should the other motor 310E, 312E fail.
[0030] FIG. 5 depicts a schematic diagram of a window management
system 400 (WMS). In general, the WMS 400 includes a WMS CPU 402
that receives inputs from sensors such as interior and exterior air
temp, time, various weather conditions such as wind velocity,
barometric pressure, rain sensors, anti-pinch features, etc.
Certain of these sensors may be integrated with the window unit
and/or window unit frame, if desired. The WMS CPU 402 has outputs
to the drive motors and actuators that slide the sash and panel.
The WMS CPU 402 takes these inputs and additional inputs (either
from remote controls or manual switches), analyzes the inputs, and
sends outputs to control the drive motors and other functions. The
WMS CPU 402 also senses and controls the output of the solar cells
and battery capacity, and switches the power to the motors and WMS
CPU 402 from the battery, e.g., to a 120V AC grid. In examples, the
120V AC input is transformed to 12 DC when solar cell output is not
sufficient. Thus, each window unit in a bank of window systems may
be individually controlled with their own dedicated WMS CPU 402. In
other examples, each window unit in a bank of windows (or a
building of windows) may be connected to a single WMS CPU 402 to be
controlled at a central location. WMS CPUs controlling single or
multiple windows may function as a connection point to tie the WMS
400 into a building management system 404. Each window system unit
may include inputs, plugs, power connection elements, etc., that
enable quick connection to control wiring, building power, etc.
These plugs and connections may be disposed on an exterior of the
window frame or within the frame itself (to be accessed by removal
of an interior or exterior panel). In other examples, the WMS CPU
402 may actuate panels based on battery power available. That is,
if the battery power is low, the system may move an outer solar
panel partially or completely so as to charge the battery.
[0031] The window systems described herein may be incorporated into
so-called "green" or "zero energy" buildings and may thus provide
LEED credits to building owners and/or tenants. Each individual
window unit may be controlled remotely or at the unit itself. If
controlled at the window itself, a panel of the window system may
include a controller in the form of buttons, switches,
touchscreen(s) including a graphic user interface, or other such
systems. A single controller disposed on a single window system may
be used to control multiple window systems. The controller may
communicate with the motors, actuators, sensors, and other elements
in other window systems via wired or wireless connections. Sensor
can include outdoor or indoor air temperature sensors, rain sensor,
or other sensors.
[0032] With these general principles in mind, a specific example of
a WMS 400 is further described in FIG. 5. In addition to being
connected to the building management system 404, the WMS CPU 402
can be connected to a number of power systems 406, exterior sensors
408, user controls 410, motor controls 412, interior sensors 414,
and sash/panel sensors 416. The power systems 406 include either or
both of building power service 406A, backup or battery power
service 406B, and one or more solar cells 406C. Battery power
service 406B can be integrated with each window unit or configured
to serve a number of units and may be particularly desirable for
operation should building power service 406A fail. Solar cells 406C
may be mounted on the exterior side of the frame and/or to the
exterior panels and supply power to the battery power service 406B
or directly to the WMS CPU 402. Additionally, solar cells 406C may
be integrated into the panel so as to generate additional solar
power when the panel is in the closed position. The solar cells
406C may be remotely mounted if necessary and it may be sized to
power an individual window unit. Additionally, a solar cell 406C
may be sized and configured to provide electrical power for the
building, for example, by delivering power back to the building
power service 406A. Excess power generated may be delivered to an
electrical grid.
[0033] Exterior sensors 408 may include weather sensors 408A and
solar sensors 408B. Weather sensors 408A contemplate outdoor air
temperature sensors, rain sensors, wind sensors, sensors that
measure barometric pressures, and other sensors. Information
derived from these sensors can be used to optimize functionality of
the WMS 400. For example, activation of a rain sensor and a wind
sensor may cause the WMS CPU 402 to close all sashes on a side of a
building that may be susceptible to rain ingress. A desirable
reading from the solar sensor 408B may cause the WMS CPU 402 to
ensure movable solar panels are in place to receive an optimum
amount of solar power. Other configurations and functionalities are
contemplated.
[0034] User controls 410 contemplate any device that be activated
by a user (either remotely or local to a window unit) so as to
control come aspect of window operation. For example, a controller
410A may be a simple open/close switch to allow a user to operate
the sash and or panel of the window. The controller 410A may also
allow direct interaction with one or more functions of the window
management system 400, via the WMS CPU 402. Indeed, each window may
include a controller (e.g., a GUI) that allows a user to control
any and all functions of the WMS 400, or a subset thereof. A panic
button 410B may be incorporated such that, when activated, both the
sash and the panel open to allow emergency egress via the window
unit. An alarm may also be sent, e.g., to the building management
system 404. Other configurations and functionalities are
contemplated.
[0035] Motor controls 412 include actuators to actuate sash
motor(s) 412A, panel motor(s) 412B, clutches 412C, and can also
include overload sensor(s) 412D to detect potential problems
associated with the motors. The operation of the motor controls
would be apparent to a person of skill in the art. Interior sensors
414 include those that can sense or otherwise detect a condition in
an interior of a building, either proximate a particular window
unit, or elsewhere. These sensors include fire/smoke sensors 414A,
HVAC sensors 414B, light level sensors 414C, temperature sensors
414D, and occupancy sensors 414E. Output from these sensors can
trigger the WMS CPU 402 to take certain actions. For example, the
WMS CPU 402 may open the windows and open the panels when the HVAC
system is in a 100% outside air mode (to take advantage of free
cooling available based on building load and outside temperature).
By simply allowing air to escape the building via the open windows,
power exhaust fans on an HVAC unit need not be operated to draw air
through HVAC return ductwork, further saving on energy costs. In
another embodiment, the sash may be kept closed and a natural or
powered ventilator could be incorporated into the interior and
exterior panels of the window system. Panels may be closed when
occupancy sensors 414E do not detect the presence of room
occupants, which may save on heating costs, if the panels are
insulated and cover the glass sash. Other functions based on
outputs of certain interior sensors 414 are contemplated.
[0036] Sash/panel sensors 416 may detect conditions directly
related to the sash or panel. For example, a proximity sensor 416A
may detect the proximity of, e.g., a user's arm, within the window
opening and not operate the sash and/or panel even if instructed to
do so by the WMS CPU 402, for the user's safety. An obstruction
sensor 416B may detect an obstruction blocking movement of the sash
or panel (e.g., a branch that may have fallen into the window) and
prevent further movement (or reverse movement) of the panel so as
not to cause damage thereto. An intrusion sensor 416C may detect a
force applied to, e.g., an exterior of the sash, which would signal
the WMS CPU 402 to active closure of the panel to further secure
the building. An egress sensor 416D may detect a similar force
applied to an interior of the sash and automatically open the sash
and/or panel. Other sensors and functionalities are
contemplated.
[0037] FIG. 6 illustrates one example of a suitable operating
environment 600 in which one or more of the present examples may be
implemented. This is only one example of a suitable operating
environment and is not intended to suggest any limitation as to the
scope of use or functionality. Other well-known computing systems,

storage, magnetic cassettes, magnetic tape, magnetic disk storage
or other magnetic storage devices, solid state storage, or any
other medium which can be used to store the desired information.
Communication media embodies computer readable instructions, data
structures, program modules, or other data in a modulated data
signal such as a carrier wave or other transport mechanism and
includes any information delivery media. The term "modulated data
signal" means a signal that has one or more of its characteristics
set or changed in such a manner as to encode information in the
signal. By way of example, and not limitation, communication media
includes wired media such as a wired network or direct-wired
connection, and wireless media such as acoustic, RF, infrared and
other wireless media. Combinations of the any of the above should
also be included within the scope of computer readable media.
[0040] The operating environment 600 may be a single computer
operating in a networked environment using logical connections to
one or more remote computers. The remote computer may be a personal
computer, a server, a router, a network PC, a peer device or other
common network node, and typically includes many or all of the
elements described above as well as others not so mentioned. The
logical connections may include any method supported by available
communications media. Such networking environments are commonplace
in offices, enterprise-wide computer networks, intranets and the
Internet.
[0041] In some examples, the components described herein comprise
such modules or instructions executable by computer system 600 that
may be stored on computer storage medium and other tangible mediums
and transmitted in communication media. Computer storage media
includes volatile and non-volatile, removable and non-removable
media implemented in any method or technology for storage of
information such as computer readable instructions, data
structures, program modules, or other data. Combinations of any of
the above should also be included within the scope of readable
media. In some examples, computer system 600 is part of a network
that stores data in remote storage media for use by the computer
system 600.
